The present invention discloses a method of manufacturing micronized sandstone obtained from ceramics or industrial wastes of ceramic manufacturing, such as white paste, natural stones or clinker, including TiO2 as bio-additive, and product obtained by the micronized sandstone thereof. The ceramics and industrial wastes of ceramic are grinded in several steps and the resultant powders are collected by means of individual filters and further combined in a nanopowder micronizer for posterior treatment, where TiO2 hydrolyzed can be optionally added. This micronized sandstone comprising the bio-additive TiO2 is used in the production of plasters, mortars, grouts and/or as additive for paints and/or epoxy enriched with TiO2. The micronized sandstone bio-additive with TiO2 can be additionally subjected to two optional embodiments of the invention: treatment with or without the use of a pigment. In order to obtain the final product that can be used in the production of blocks, floors and other products of various sizes, an agglomerating agent combined with TiO2 is added to the micronized sandstone comprising the bio-additive TiO2, either in an aqueous solution or as a dry product, optionally including colored oxides.
